Abstract:Abstract The dense yittria-stabilized zirconia membrane tube was prepared by using pyridine as dispersant by vacuum casting. The thickness of the membrane in the tube is 0. 2 mm and the length is 140 mm. The effect of sintering temperature on the density and ionic conductivity of the samples was studied. The solid oxide fuel cell(SOFC) was made of the YSZ membrane tube, which was sintered at 1 650 for 2 h. The electrochemical property of the SOFC was studied from 500 to 900 , hydrogen and city coal gas were used as fuel, respectively. The research shows that the YSZ membrane tube with a high quality and density can be prepared by the vacuum casting, the relative density of the YSZ membrane tube reaches 98.1% of theoretical density at sintering temperature of 1 600 , approaching the theoretical density. The maximum of open voltage is 1. 213 V, and the maximum of output power is 0. 48 W. The electrical property of the SOFC with hydrogen as fuel is superior to that of the one with city coal gas as fuel.
Keywords:Vacuum casting  YSZ electrolyte membrane tubes  Sintering properties  SOFC
